On 6 December 1992 a referendum was to be held in Switzerland on a federal resolution on the accession to the [[European Economic Area|European Economic Area (EEA)]].<ref name=":08">{{Cite book |last=Kreis |first=George |url=https://www.taylorfrancis.com/chapters/edit/10.4324/9781003038719-2/looking-back-georg-kreis |title=Looking back : 1992 as a critical juncture |date=2021 |publisher=Routledge |isbn=978-1-003-03871-9 |language=en |doi=10.4324/9781003038719-2}}</ref> In correspondence with the [[customs union]] between the two countries, a similar referendum was to be held in Liechtenstein at a similar time.<ref name=":23">[http://eed.nsd.uib.no/webview/index.jsp?study=http%3A%2F%2F129.177.90.166%3A80%2Fobj%2FfStudy%2FLIREF1992_SUM_Display&mode=cube&v=2&cube=http%3A%2F%2F129.177.90.166%3A80%2Fobj%2FfCube%2FLIREF1992_SUM_Display_C1&top=yes Dataset: Liechtenstein: Referendum on the Agreement of European Economic Area 1992] {{Webarchive|url=https://web.archive.org/web/20190126181102/http://eed.nsd.uib.no/webview/index.jsp?study=http%3A%2F%2F129.177.90.166%3A80%2Fobj%2FfStudy%2FLIREF1992_SUM_Display&mode=cube&v=2&cube=http%3A%2F%2F129.177.90.166%3A80%2Fobj%2FfCube%2FLIREF1992_SUM_Display_C1&top=yes |date=26 January 2019 }} European Election Database</ref>

Hans-Adam II called for the referendum to be held before the [[1992 Swiss referendums|corresponding referendum in Switzerland]], against the countries custom union and the wishes of the government with the Landtag of Liechtenstein. On 28 October 1992, he threatened to dismiss the Landtag and prime minister [[Hans Brunhart]] over the dispute and appoint an acting Prime Minister in his place. In response, approximately 2000 people demonstrated in front of the government house in Vaduz. In the same day, the government and Hans-Adam II negotiated and came to an agreement that scheduled the referendum after the corresponding one in Switzerland, though notably it affirmed that Liechtenstein would commit to agreements with the EEA despite the result in Switzerland.<ref name=":45">{{Cite web |last=Marxer |first=Wilfried |date=31 December 2011 |title=Staatskrise (28.10.1992) |url=https://historisches-lexikon.li/Staatskrise_(28.10.1992) |access-date=18 February 2024 |website=[[Historisches Lexikon des Fürstentums Liechtenstein]] |language=de}}</ref>
